David Hildenbrand 98a729f077 virtio: reenable config if freezing device failed ... [ Upstream commit 310227f428 ] Currently, we don't reenable the config if freezing the device failed. For example, virtio-mem currently doesn't support suspend+resume, and trying to freeze the device will always fail. Afterwards, the device will no longer respond to resize requests, because it won't get notified about config changes. Let's fix this by re-enabling the config if freezing fails.
